To a whom it may concern:

Be it known that I, SAMUEL A. DONNELLY, a citizen of the United States,residing at Chicago, county of Cook, and State of Illinois, haveinvented a new and Improved Truss, of which the following is aspecification.

My invention particularly relates to the treatment of hernia by the useof a truss havin a large range of adjustment, positive hoIding devices,and a pad that properly holds a hernia, and that is cool, clean, andsanitary.

Althou h this-truss is of the sprin -truss order, it a so can be madewith a flexib e belt, if desired. The ads of my truss can be madeflexible or ohcast or sheet metal, if desired, or both. I preferably usealuminium because of its non-corrosive, clean, and lastin qualities; butI also may use rubber or other material for my pads and other parts.

In the accompanying drawings, Figure 1 is a front view of part of mytruss, showing my truss-pad. Fig. 2 is an inside view of my truss-pad.Fig. 3 is a sectional view of my truss-pad with the concave connections.Fig. 4 is another sectional view of my trusspad with the convexconnections. Fig. 5 is a side view of the end clip of my truss-springwith radiating notches. Fig. 6 is a view of the adjusting-washer,showing the radiating notches. Fig. 7 is a view of the adjustingwasher,showing the parallel notches. Fig. 8 is a sectional view of theadjusting-washer, showing it made convex. Fig. 9 is a sectional view ofthe adjusting-washer, showing it made concave. Fig. 10 is a bottom viewof the adjusting-lever, showing the parallel notches.

The pad B, as can be seen on the difierent views-Figs. 1, 2, 3, 4, is ofa half-circular dish-shaped construction having one part of its edgestraight, whichconforms more nearly.

to fitting the groin where the most of the ruptures occur than otherpads nowmade. This I consider the best shape for fitting and holding thegeneral run of ruptures, as it conforms better between the abdomen andlower In the bottomof the dished pad is the rounded recess B havin thestud B for engaging the spoon-shape end I; of the adjusting-lever lfibymeans of the washer B and the thumb-nut B The spoon-shaped end I), has ahole sufficientl lar e as to permit the pad to be oscillate su 'cientlyas to be conformed and adjusted to the rupture and then secured by thethumb-nut B The opposite end of the lover I) is secured to the endclipfl of the spring A by means'of'the stud()"j'the"ad justing-washer CC, the washer'C, afi'd' the nut C. If desired, the stud-screw C can-be?made into a thumb-screw and" then thenut C can be dispensed with. 1 Theadjusting leVer b 'it will be noticed," has a parallel notched endbfThse" paral lel notches engage the parallel'notchesfi of theadjusting-washer C G. I osthvnut O bein unscrewed, the angle oftheleverb. ca be a justed as to give it suificientinward ten sion to thepad B against the 'ruptur either moving the lever b backwardward-throughthe washersCC and C and" then by tightening the nutagaiiitheadjust ment is positively secured. "On the op ositei" side ofthe adjusting-washerC'C are'th'era' diating notches C. These notchesen"75 the radiating notches C of the endC 0 th L truss-springA'. i On thenut C being'unscrewed, the lever b can be moved in any lateraldirection,so that the pad B can be adjusted tothe ru'p l' ture, and thenon the nut C being tightened the radiating notches mesh into each other,so as positively to secure the adjustment" from any lateral movement,but, preferably," I contem late that on the unscrewing of the nut C t eadjusting-lever be adjusted in} any direction desired oruntil limitedbefore the nut C" is again tightened up. Th d. I?

justing-washers, it willgb'seen have .a projecting part D, havingtlfereofithe stud-pin C being for the urpo'sei of allowing the] strap Eto be attac ied thereto either to the front or to the back of the saidprojecting part D by attaching the strap or bandto the ackof theprojection D. It is more positively 5 held in place by the down andoutwardpres sure of the abdomen inholding the strap to the back of theprojection D. Also as trusses have'a tendency to move upward and a'wa'yffrom the rupture, due to the action of the lower muscles and limbsworking against the ad, I therefore have devised this projection D as acounter device inke'eping 'thepad downward and in place hy'thedo'wnwardressure of the abdomen on the strap "ar hand, said band or stra i beingheld higher up than usual against the abdomen by'thc'j use of theprojection D, therefore adding pressure in keeping the truss and paddown: ward and in place in holding the rupture but" either with orwithout the projecting part D,

and the stra E can then be connected to the stud b on t eadjusting-lever b By referring to'Figs. 8 and 9 it can be seen that theadjusting-washers C C can be either made concave or convex and the leverb bent to conform to either kind of said washers. I do this for thereason that on a high-rimmed ad, such as shown on Fig. 4, it would bebest to use a concave adjusting-washer, and on a low-rimmed pad, asshown on Fig. 3, a convex adjusting-washer, as it then allows more roombetween the lever and the rim of the pad. My truss may be made witheither ad. P I have shown both kinds of washers and levers conforming tothe same, as can be seen on Figs. 3, 4, 8, 9. Although I have not shownthe washers C C made with radiating notches on both of its sides, theymay be made'so that the projection D may be lowered or raisedindependent of the s ringclip or adjustable lever, and although have notshown the lever I) made having its end I) with the radiating notches itmay be so notched, when it then will be ready to directly engage theradiatin notches of the clip 0 of the spring A. also can dis ense withthe adjustin -washer'C 0 when do not desire an inwar adjustment of mytruss-pads. The pad B when made of such material as will not be ofsufficient strength as to hold firmly the screw-stud B, I wil thenreinforce the pad by using the reinforcement B in supporting thestud-screw B, and also in allowing more thread to surround the said studscrew for the wear and extra strain that it will have to stand in makingthe different adjustments. As I further will use this stud-screw B ,inconjunction with the fieldble diaphragm B B, and the lug-pad B, (seeFig. 3,) as an adjustable plug for plu ging up and holding ruptures ofvariab e sizes, as this adjustment can be nicely made by either screwinginward or outward against the diaphra m the stud-screw B from the pad B,(see ig. 3,) I preferably use rubber for my dia hragm, an it is held inplace on the pad y the flange B contracting itself around the pad. Theplug-pad may be an integral part of the stud-screw B or it may be aseparate art of said screw, as may be desiredsuch, or instance, as whenit is made smaller in size it is best then to make it an integral partof said screw.

Where it may be undesirable, the diaphragm may be dispensed with. Alsowhere 1t may be desirable to use a simple pad the pad B (shown on Fig.4) may suflice for the not to catch on the underwear or make a lumpyappearance in the location of the rupture.

What I claim, and desire to secure by Letters Patent, is
